Omicron is more transmissible but may have milder symptoms for many people, expert says

If the first reports coming out of South Africa are correct, Omicron might be more transmissible than the current dominant Covid-19 strain, Delta, but cause less severe symptoms for many people. A leading expert says that, if the new strain does turn out to be milder for some people, that creates a new set of problems.
